Inox Wind Brand Guidelines: The 2009 Turbine Maker From an Industrial-Gases Family

A 2009 offshoot of an industrial-gases family.

Inox Wind Limited was incorporated on 9 April 2009 as a public limited company, its investor page says, with its registered office in the Una district of Himachal Pradesh; it received its certificate to commence business six days later. English Wikipedia’s article on the Inox Group says the wind business was promoted by Devansh Jain, son of Vivek Jain, as the family moved into wind energy that year.

The Inox name is older than the turbines. Wikipedia says it comes from “Industrial Oxygen Company,” the industrial-gases business that Devendra Kumar Jain set up in Pune in 1963, and that the family’s commercial roots go back to a paper and newsprint trading house founded in the 1920s. Over the following decades the group added cryogenic tanks, refrigerants and fluoropolymers, and a cinema chain.

In 2021 a family settlement divided the group in two, Wikipedia says. One branch, led by Pavan Jain, kept industrial gases and cryogenic equipment under the Inox Group name; the other, led by Vivek Jain, took Gujarat Fluorochemicals, Inox Wind and its parent Inox Wind Energy, grouped as the INOXGFL Group. Wikipedia puts Vivek Jain’s family stake in Inox Wind at about 67 per cent, and says that from 2023 the INOXGFL branch also moved into solar manufacturing through new companies such as Inox Clean Energy. Both branches still use the Inox name. Inox Wind’s own website presents it as part of INOXGFL, with a head office in Noida, near Delhi.

Turbines for low-wind sites.

Inox Wind makes complete wind turbine generators and sells them on four models, it says: turnkey projects from wind study to commissioning, limited-scope work, equipment supply alone, and operation and maintenance. Its turbines use doubly fed induction generator technology from its licensing partner AMSC, the Austrian subsidiary of the American Superconductor Corporation, according to its technology-partner page, and the company says they are designed for the low wind speeds found across much of India. The same page says AMSC Windtec designs had been installed and commissioned for 17.7 GW worldwide as of June 2022.

Two platforms make up the current range. The INOX DF 113 is a 2 MW machine with a 113-metre rotor and hub heights from about 90 to 120 metres. The INOX DF 145 is rated at 3 MW, extendable to 3.3 MW, with a 145-metre rotor and conical tubular steel towers of 100, 120 or 140 metres; the company describes it as one of India’s largest wind turbines. Both use blades of epoxy and glass fibre, its specification sheets say.

The company builds the main parts itself. Its investor page says blades and tubular towers come from plants in Gujarat and Madhya Pradesh, and hubs and nacelles from a plant in Himachal Pradesh and another in Gujarat. Its manufacturing page names nacelle and hub works at Bhuj and Ahmedabad and blade plants at Rohika in Gujarat and Barwani in Madhya Pradesh, with blade design support from WINDnovation and Italian-made rolling mills for the towers. The company says its blade plants can make blades for rotors from 100 metres up to 145.4 metres across, that its towers range from 92 to 120 metres, with 140-metre tubular steel towers added more recently, and that it outsources tower fabrication when orders require it. Operation and maintenance sits in a sister company, Inox Green Energy Services, which Wikipedia says was listed on the Indian stock exchanges in 2022.

Towers, blades and nacelles.

Wind turbine makers sell machines that few people ever see up close, so the pictures they publish do much of the work of a brand. The most familiar image is the finished turbine: a white tower and three blades on a ridge, across farmland or in a line out at sea, often shot at dawn or against a clear sky. Onshore and offshore are presented as two different worlds, one of fields and hills, the other of open water and service vessels.

The second set of images is about scale and movement. Makers like to show a single blade strapped to a long trailer on a country road, or rows of blades, towers and nacelles waiting on the quay of a port before being loaded onto ships. Port hubs and installation vessels have become a picture in their own right as offshore wind has grown.

Inside the factory, the pictures turn to process: nacelles lined up in high, bright halls, generators and hubs on assembly stands, and blade moulds the length of the building, with workers in overalls and helmets for scale. Service teams make up the last familiar scene, technicians clipped on at the top of a nacelle with the landscape far below, or descending a blade on ropes.

Behind the images is a heavy industry with a small number of large makers. BloombergNEF reported that 169 gigawatts of wind capacity were added worldwide in 2025, about 95 per cent of it onshore, and that Chinese makers took the top six places in its supplier ranking for the first time. This guide sets out what can be checked about each brand — who founded it, who owns it and where it says its turbines, blades and towers are made — and marks clearly what rests only on the company’s own word.

A listing, a downturn, a merger.

Inox Wind went public in the spring of 2015. Its shares began trading on India’s BSE and NSE on 9 April 2015 and ended the first day about 35 per cent above the offer price, CleanTechnica reported on 13 April 2015; the offer of 23.2 million shares drew bids for 431 million, noting that the only other listed Indian wind energy company at the time was Suzlon Energy.

The years that followed were harder. Wikipedia says the business grew quickly between 2010 and 2016, but a 2017 change in Indian policy from feed-in tariffs to competitive bidding brought a long downturn for the country’s wind sector, during which Inox Wind’s debt rose sharply before capital from its promoters supported a recovery. In June 2025 the Chandigarh bench of the National Company Law Tribunal approved the merger of the holding company Inox Wind Energy into Inox Wind, Energetica India reported on 11 June 2025, removing a layer from the INOXGFL Group’s structure; the company said the move would reduce Inox Wind’s liabilities.

The company puts the turbines it has installed across India at more than 3.1 GW, and it describes itself as India’s leading wind energy solutions provider.

For a design guide, Inox Wind shows how a family name that began with an industrial-gases company can carry into a new sector. Compare Suzlon, the Pune turbine maker that was India’s other listed wind company in 2015, and Vestas.
